[0038] In actual application, when the AGV car with the packaging carton reaches the cigarette packing station, the AGV car is first stopped below the space 30 for accommodating the AGV car between the double-row synchronous conveyors 6 at the cigarette packing station, and then the lifting platform at the top of the AGV car is driven to lift the packaging carton to a position slightly higher than the top of the double-row synchronous conveyor 6, and then the posture of the AGV car is adjusted so that the packaging carton on the lifting platform at the top of the AGV car is placed on the conveying position on the top of the double-row synchronous conveyor 6; at this time, the first chain lifting element 4 on the first frame 1 and the second chain lifting element 5 on the second frame 2 are first driven to move by the chain driving element, and under the movement of the first chain lifting element 4 and the second chain lifting element 5, the double-row synchronous conveyor 6 with the packaging carton is lifted to the feeding end of the packaging conveying line at the cigarette packing station, and then the double-row synchronous conveyor 6 is driven to run, so that the packaging carton on the conveying position on the top of the double-row synchronous conveyor 6 is fed from the discharging end of the double-row synchronous conveyor 6 to the packaging conveying line at the cigarette packing station, thereby solving the problem that the AGV car needs to use the forks on the forklift to lift the packaging carton from the lifting platform to the packaging conveying line directly above the packaging station, and then the forks are separated from the packaging carton, so that the packaging carton can be transferred to the packaging conveying line.

[0039] Please refer to Figure 5 、 Figure 6 、 Figure 7 、 Figure 4 and Figure 1The first rack 1 for mounting the first chain lifting member 4 and the chain driving member 3 and the second rack 2 for mounting the second chain lifting member 5 and the chain driving member 3 are racks of the same structure, and the first rack 1 and the second rack 2 each comprise a base 7, a first upright column 8 and a second upright column 9; the base 7 is of a rectangular cavity structure with a rounded corner at one end, the first upright column 8 and the second upright column 9 are each of a cavity structure with an open bottom, and the openings 10 at the top of the base 7 respectively communicate with the openings at the bottom of the first upright column 8 and the second upright column 9, that is, the cavities of the base 7, the first upright column 8 and the second upright column 9 are interconnected to form installation spaces for the first chain lifting member 4 or the second chain lifting member 5.

[0040] Specifically, the assembly relationship of the chain driving member 3, the first chain lifting member 4 and the first rack 1 or the chain driving member 3, the second chain lifting member 5 and the second rack 2 is as follows: the base 7 in the first rack 1 and the base in the second rack 2 are respectively rotationally connected with part of the chain driving member 3, one end of the chain driving member 3 is connected with the first chain lifting member 4 arranged in the inner cavities of the base 7, the first upright column 8 and the second upright column 9, and the other end of the chain driving member 3 is drivingly connected with the second chain lifting member 5 arranged in the inner cavities of the other base 7, the other first upright column 8 and the other second upright column 9, the lifting end of the second chain lifting member 5 passes through the through slot 11 on the side wall of the first upright column 8 and the second upright column 9 and is connected with one outer side wall of the double-row synchronous conveying machine 6, and the lifting end of the first chain lifting member 5 passes through the other through slot 11 on the side wall of the other first upright column 8 and the other second upright column 9 and is connected with the other outer side wall of the double-row synchronous conveying machine 6, so that the chain driving member 3, the first chain lifting member 4, the second chain lifting member 5 and the double-row synchronous conveying machine 6 are assembled with the first rack 1 and the second rack 2.

[0041] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9The first chain lifting member 4 and the second chain lifting member 5 for lifting the double-row synchronous conveying machine 6 loaded with the carton to the feeding end of the packaging processing conveying line at the carton loading station are chain lifting members of the same structure. The first chain lifting member 4 and the second chain lifting member 5 each include a driving sprocket 12, a first driven sprocket 13, a second driven sprocket 14, a third driven sprocket 15, a fourth driven sprocket 16, a fifth driven sprocket 17, a sixth driven sprocket 18, a lifting chain 19, and a lifting strip 20. The driving sprocket 12 is connected with the chain driving member 3 and rotates coaxially with the chain driving member 3. The lifting chain 19 is used to transmit the rotation of the driving sprocket 12 to the first driven sprocket 13, the second driven sprocket 14, the third driven sprocket 15, the fourth driven sprocket 16, the fifth driven sprocket 17, and the sixth driven sprocket 18 to drive the driving sprocket 12, the first driven sprocket 13, the second driven sprocket 14, the third driven sprocket 15, the fourth driven sprocket 16, the fifth driven sprocket 17, and the sixth driven sprocket 18 to form a guide transmission. In addition, the lifting chain 19 is used to drive the lifting strip 20 to move upward or downward in the vertical direction to drive the double-row synchronous conveying machine 6 connected with the lifting strip 20 to move upward or downward in the vertical direction.

[0042] Specifically, the chain driving member 3 is connected with the driving sprocket 12 in the cavity of the two bases 7 at both ends, respectively.

At this time, since the lifting strips 20 are connected with the outer side wall of the double-row synchronous conveying machine 6, the double-row synchronous conveying machine 6 loaded with the packaging cartons is indirectly driven to move upward in the vertical direction, so as to be lifted in the vertical direction to the feeding end of the packaging processing conveying line at the carton loading station, which facilitates the subsequent conveying of the packaging cartons loaded on the double-row synchronous conveying machine 6 to the packaging processing conveying line.

[0044] It should be noted that, in order to form a closed loop transmission between the driving sprocket 12 on the first rack 1 and the second driven sprocket 14 rotatably connected with the second upright column 9, the fifth driven sprocket 17 rotatably connected with the second upright column 9 and the first driven sprocket 13, the third driven sprocket 15, the fourth driven sprocket 16 and the sixth driven sprocket 18 rotatably connected with the base 7, the driving sprocket 12, the first driven sprocket 13, the second driven sprocket 14, the third driven sprocket 15, the fourth driven sprocket 16, the fifth driven sprocket 17 and the sixth driven sprocket 18 on the second rack are arranged as follows:
